Binned CTD data from R/V New Horizon cruise NH1106 in Guaymas in 2011 (Jumbo Squid Physiology project)

Expand/Collapse All

Description

1-meter binned CTD data from 20 casts made during the NH1106 cruise in the Guaymas Basin. Data include figures of each cast (as PDF files) made using the Seabird SeaPlot program of SBE Data Processing.

Methods & Sampling

See the header file (.txt) from CTD cast 01.

Calibration Sheets (PDF files):
primary temperature sensor (SBE3)
primary conductivity sensor (SBE4)
oxygen sensor (SBE43)
PAR sensor (Biospherical QSP-2300)

Data Processing Description

1 m binning was carried out with SBE Data Processing. Oxygen was processed using tau and hysteresis corrections (as recommended by Seabird for the SBE43 sensor).

BCO-DMO Processing Notes: parameter names modified to conform with BCO-DMO naming conventions; removed 'flag' column (all values were 0).

CTD Sea-Bird SBE 911plus

Supplied Name: CTD SBE 911plus

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics
